Description

TECHNICAL FIELD

The present invention relates to aminophenol derivatives having binding inhibition against cholecystokinin receptors including gastrin receptor and useful as therapeutic agents for digestive diseases and central nervous system diseases.

BACKGROUND ART

Cholecystokinin (CCK) is a brain/gastrointestinal tract hormone and has a close connection with the central nervous system and the gastrointestinal tract. CCK receptors are categorized into two groups: CCK-A receptor which is found primarily within components of the digestive tract such as the pancreas or the biliary system and CCK-B receptor which is found in the brain. CCK-A receptor is considered to significantly participate in control of gastrointestinal motility and pancreatic juice system. CCK-B receptor is considered to significantly participate in appetite regulation and psychic activities.

On the other hand, Gastrin, known as a hormone stimulating gastric acid secretion and CCK have in common five C-terminal amino acid residues. Therefore, both are called members of the gastrin/CCK family. Gastrin receptor, which may be found in the gastrointestinal tract, pancreas, and the biliary system, are primarily found in gastric mucosal cells (parietal cells) and participate in the control of gastric acid and pepsin secretion. The gene encoding CCK-B receptor and gastrin receptor were cloned, and as a result, it was found that the amino acid sequences of the two receptors are identical (Y-M. Lee, et al., J. Biological Chem. 268 (11) 8164-8169, 1993).

As described hereinbefore, there are two groups of CCK receptors, and the CCK-B receptor is considered to be identical to the gastrin receptor. Various diseases are considered to manifest themselves through these receptors.

Accordingly, development of compounds having strong binding inhibition against one of CCK-A or gastrin (CCK-B) group of receptors is desired.

Accordingly, a general object of the present invention is to provide a compound exhibiting strong binding inhibition against members of either the gastrin (CCK-B) receptor or the CCK-A receptor.

Methods for preparing the compounds of the present invention will next be described.

Among the compounds of the present invention, those having an asymmetric carbon in the molecule may be prepared by ultimately performing optical resolution using known techniques or by performing optical resolution of intermediates using known techniques, thereby obtaining optically active compounds. When optically active starting materials are used, optically active final compounds can be obtained.

The compounds of the present invention may be prepared, for example, by any of the following methods A through N.

Method A: ##STR3## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, X, and A have the same meanings as defined above, and CDI stands for N,N'-carbonyl diimidazole. If any of the compounds involved in the above reaction has one or more substituents which may affect the reaction, they must be protected using suitable protective groups commonly used in the synthetic chemistry which remain unaffected by the reaction prior to the reaction.

Briefly, compound (1) of the present invention can be prepared by reacting a compound (2) with N,N'-carbonyl diimidazole (CDI) to yield a compound (3), and subsequently, reacting the compound (3), being separated or unseparated, with an amine derivative (4).

The reaction may be carried out by reacting compound (2) with CDI in, for example, an inert solvent such as tetrahydrofuran or N,N-dimethylformamide at 0-60.degree. C., preferably at room temperature, to yield an intermediate, imidazolide (3), and subsequently by refluxing the imidazolide (3), without being separated, together with amine derivative (4) with heat in toluene.

Briefly, compound (1) of the present invention can be prepared by reacting a compound (2) with an isocyanate derivative (5).

If R.sup.1 has a protective carboxyl group like alkoxycarbonylalkylphenyl, or if R.sup.1 has no reactive group, the above reaction scheme may be directly carried out. On the other hand, if R.sup.1 has a free carboxy group, the carboxy group is preferably protected by, for example, an ester residue in advance.

Briefly, compound (1) of the present invention can be prepared by reacting a compound (6) with a compound (7). This reaction may be carried out by reacting compound (6) with compound (7) in a solvent such as N,N-dimethylformamide in the presence of a base such as potassium carbonate or sodium carbonate at 50-90.degree. C., preferably at 60-70.degree. C.

Compound (1) in which R.sup.5 is a group --N(R.sup.6)(R.sup.7), at least one of R.sup.6 and R.sup.7 is a phenyl group having a substituent and the substituent is a hydroxyl group may also be prepared by reductively removing the benzyl group of a compound in which the substituent on phenyl is benzyloxy on the benzene ring. This may be done by catalytic hydrogenation. Under normal circumstances, the reaction may be carried out in a hydrogen gas atmosphere of 1 atm at room temperature in the presence of a palladium-on-carbon catalyst. However, it is also possible to perform the reaction with the application of heat and pressure. The solvents generally used are methanol, ethanol, ethyl acetate, or their mixtures.

C., preferably 90-100.degree. C.

Method G:

Compound (1) in which R.sup.1 is phenyl having a substituent and the substituent is hydroxyalkyl may also be prepared by reducing a compound in which the substituent on phenyl is acyl using sodium borohydride in a solvent such as methanol, ethanol, chloroform, or dichloromethane. As reducing agents used in this reaction, other reducing agents which affect ketones or aldehydes only may also be useful.

C., preferably at room temperature.

C. and room temperature.

Method J:

Compound (1) in which R.sup.5 is a group --N(R.sup.6)(R.sup.7) may also -be prepared by reacting a compound (1) in which R.sup.5 is hydroxy with primary or secondary amine corresponding to the group --N(R.sup.6)(R.sup.7) in an inert solvent such as dichloromethane, chloroform, tetrahydrofuran, or ethyl acetate in the presence of a condensing agent such as N,N'-dicyclohexylcarbodiimide or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride at 0-40.degree. C. In the present reaction, when 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride is used as a condensing agent, a base in an amount that suffices for neutralizing hydrochloric acid is needed. To this end, under normal circumstances, an excessive amount of 4-dimethylaminopyridine may be added. As condensing agents, other condensing agents that are routinely used for forming an amide bond can also be used.

Method K:

Compound (1) in which R.sup.5 is a group --N(R.sup.6)(R.sup.7), either one of R.sup.6 or R.sup.7 is a hydrogen atom, and the other is a hydrogen atom, a methyl group, or an ethyl group may be prepared by reacting a compound (1) in which R.sup.5 is methoxy or ethoxy with concentrated ammonia water, an aqueous solution of monomethylamine, or an aqueous solution of monoethylamine without use of a solvent or in a solvent such as methanol, ethanol, or tetrahydrofuran at room temperature.

C., preferably at room temperature. In the present invention, the amount of alkoxyl group in the resulting alkoxycarbonyl alkyl group differs depending on the species of the alkyl group in the dialkylpyrocarbonate used in the reaction. Namely, if dimethylpyrocarbonate is used, compound (1) in which R.sup.1 is a methoxycarbonylalkyl-substituted phenyl group can be obtained.

Method M:

By refluxing with heat a compound (1) in which R.sup.1 is a phenyl group which may have a substituent and the substituent is an alkoxycarbonylalkyl group in alcohol in the presence of titanium (IV) isopropoxide, it is possible to convert the compound (1) into a compound (1) in which R.sup.1 is a phenyl group substituted by an alkoxycarbonylalkyl group, which group corresponds to the alcohol (with the case where methanol is used as the alcohol being excluded). For example, by refluxing, with heat, a compound in which R.sup.1 is a phenyl group substituted by a methoxycarbonylalkyl group in isopropanol in the presence of titanium (IV) isopropoxide, a compound (1) in which R.sup.1 has been substituted by an isopropoxycarbonylalkyl group can be prepared.

Method N:

When a compound (1) in which R.sup.1 is a phenyl group which has been substituted by an alkoxycarbonyl group, alkoxyalkyl group, or an alkoxyalkyloxy group is processed using an acid or an alkali, it is possible to obtain a compound (1) in which R.sup.1 is a phenyl group which may have a substituent and the substituent is a carboxyl group, carboxyalkyl group, or a carboxyalkyloxy group. In order to obtain a compound (1) in which the alkoxyl group is a tertiary butyl group, an acid, preferably trifluoroacetic acid, may be used in the presence of a solvent such as dichloromethane or in the absence of a solvent. In order to obtain a compound (1) in which the alkoxyl group is another alkyl group, an aqueous alkali hydroxide solution such as an aqueous NaOH solution may be used. Compound (1) having a carboxyl group can be converted into a corresponding carboxylic acid salt by processing with an equimolar amount of an alkali hydroxide.

If any of the compounds involved in the above reaction has one or more substituents which may affect the reaction, they must be protected using suitable protective groups commonly used in the synthetic chemistry which remain unaffected by the reaction prior to the reaction.

As protective groups for oxygen and sulfur in the starting compound (8), benzyl and benzhydryl are preferred. As amino protective groups represented by R.sup.11, tertiary butoxycarbonyl is preferred among others. As halogen atoms represented by Y and Z, bromine, chlorine, and iodine are preferred.

The reaction of compounds (8) and (9) may be carried out, for example, in an inert solvent such as dichloromethane, chloroform, tetrahydrofuran, or ethyl acetate in the presence of a condensing agent such as N,N'-dicyclohexylcarbodiimide or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride at a temperature between 0.degree.

After the above-described reactions are completed, target compounds can be separated from the reaction mixtures and purified by routine methods such as recrystallization, any of a variety of chromatography procedures, or any suitable combination of these. Salts of the compound (1) of the present invention can be obtained by treating a free acid with an alkali hydroxide, etc., by routine methods, or by treating a free base with hydrochloric acid, etc., by routine methods.

The thus-obtained compounds (1) of the present invention and their salts and optical isomers of the compounds (1) and the salts have potent gastrin receptor binding inhibition or CCK-A receptor binding inhibition. Some of the compounds (1) exhibit selectivity toward the gastrin receptor and some other compounds (1) exhibit selectivity toward the CCK-A receptor.

As described hereinbefore, two types of CCK receptors are known: those which are found primarily within components of the digestive tract such as the pancreas or the biliary system (CCK-A receptor) and those which are found in the brain (CCK-B receptor). The CCK-A receptor is considered to significantly participate in motility of gastrointestinal tract and secretion of pancreatic juice, and the CCK-B receptor is considered to participate in psychic activities and appetite regulation in the cerebrum. Gastrin receptor which is primarily found in gastric mucosal cells (parietal cells) and is considered to be identical to CCK-B receptor participates in the control of gastric acid and pepsin secretion. Accordingly, binding inhibitors of these receptors are considered to be useful in the prevention and treatment of digestive tract diseases and central nervous system diseases which are closely connected to their respective peptide hormones.

Among the compounds (1) of the present invention, salts of compounds (1), and optical isomers of compounds (1) or salts of compounds (1), particularly preferred ones are those having potent gastrin receptor binding inhibition and exhibiting markedly higher affinity to gastrin receptors than to CCK-A receptors. Such compounds are useful as preventive and therapeutic agents for peptic ulcers, gastritis, rectal/colonic cancer, Zollinger-Ellison syndrome, and anxiety syndrome.

Medicines containing the compounds of the present invention may be prepared into injection preparations for intravenous injection, intramuscular injection, or for subcutaneous injection, and administered to subjects in need thereof by injection. Alternatively, they may be administered orally or transdermally. Intravenous administration and oral administration are preferred.

When the compounds of the present invention are used as medicines, the compounds of the invention are preferably formulated into pharmaceutical compositions containing the compounds and pharmaceutically acceptable carriers. As pharmaceutical compositions, there are compositions for oral administration and injection compositions. Compositions for oral administration include tablets, powders, granules, capsules, solutions, syrups, elixirs, and oil-base or water-base suspensions. When injection compositions are formulated, the compositions may include stabilizers, preservatives, solution adjuvants, etc.

The dose of the compounds of the present invention to a human subject varies depending on his disease, conditions, body weight, etc. In general, a dose of 1-1,000 mg/day, which is administered at a time or in several divided times, is preferred in cases of oral administration.

Test Example 1

Inhibition of binding against receptors

The following receptor binding test was performed so as to investigate biological activities of the compounds of the present invention.

Test Method:

Separation of human CCK-B/gastrin receptor cDNA clone, separation of human CCK-A receptor cDNA clone, and expression of respective cloned receptors in heterologous cells.

cDNA of human CCK-B/gastrin receptor cDNA (Pisegna et al.: Biochem. Biophys. Res. Commun., 189, 296-303, 1992) and human CCK-A receptor cDNA (Ulrich et al.: Biochem. Biophys. Res. Commun., 193, 204-211, 1993) have already been isolated. The cDNAs having the reported nucleotide sequences were prepared using routine genetic engineering techniques. The isolated human CCK-B/gastrin receptor cDNA or human CCK-A receptor cDNA was integrated in an expression vector using routine genetic engineering techniques and transfected to CHO cells derived from the Chinese hamster ovary so as to induce expression of respective receptors.

1) Inhibition of binding against gastrin receptor

The compounds of the present invention were evaluated by the receptor-binding assay using .sup.125 I-gastrin and human CCK-B/gastrin receptor expressed in CHO cells. CHO cells expressing the human CCK-B/gastrin receptor were cultured using a Dulbecco's modified Eagle minimum essential medium: nutrient mixture F-12 (hereinafter abbreviated as DMEM/F-12) containing 10% fetal bovine serum at 37.degree. C. in an aerobic phase of 5% CO.sub.2 and 95% air. Using a culture dish having a diameter of 16 mm (base area: 2 cm.sup.2), the cells were cultured so as to obtain 5.times.10.sup.5 cells. The cells were washed with a binding buffer (Earle's balanced salt solution containing 10 mM 4-(2-hydroxyethyl)-1-piperazine ethanesulfonic acid (HEPES) (pH 7.4), 0.1% bovine serum albumin, 2 mM glutamine, and 0.22% sodium hydrogen carbonate) twice, after which a binding buffer (0.5 ml) was added to the dish. To this binding buffer, a test compound (5 .mu.l) dissolved in dimethylsulfoxide (DMSO) was added. The reaction was then allowed to start by adding 0.01 ml (final concentration: 25 pM) of �.sup.125 I!gastrin. When a nonspecific binding amount was obtained, reaction was carried out in the presence of 1 .mu.M of non-labelled gastrin. Reaction was allowed to proceed at 37.degree. C. in an aerobic phase of 5% CO.sub.2 and 95% air, after which the cells were washed with phosphate-buffered saline (PBS). �.sup.125 I!gastrin which had not been bound to the cells was removed, and the cells were lysed by adding 1% Triton X-100 (250 .mu.l) to the dish. Radioactivity of this solution was measured by a gamma counter. A specific binding amount was obtained by subtracting a nonspecific binding amount from a total binding amount. Using the thus-obtained specific binding amount, the percentage of the value obtained from a test substance addition group with respect to that of the DMSO addition group was calculated. The percentage was subjected to Hill conversion and then a least squares method, obtaining a 50% inhibitory concentration (IC.sub.50).

A specific example showing gastrin receptor antagonizing activities of typical compounds of the present invention and a comparative compound will next be described.

2) Inhibition of binding against CCK-A receptor

Test method: The compounds of the present invention were evaluated by the receptor-binding assay using .sup.125 I-gastrin and human CCK-B/gastrin receptor expressed in CHO cells. CHO cells expressing a human CCK-A receptor were cultured using a DMEM/F-12 containing 10% fetal bovine serum at 37.degree. C. in an aerobic phase of 5% CO.sub.2 and 95% air. Using a culture dish having a diameter of 16 mm (base area: 2 cm.sup.2), the cells were cultured so as to obtain 5.times.10.sup.5 cells. The cells were washed with a binding buffer (Earle's balanced salt solution containing 10 mM HEPES (pH 7.4), 0.1% bovine serum albumin, 2 mM glutamine, and 0.22% sodium hydrogen carbonate) twice, after which a binding buffer (0.5 ml) was added to the dish. To this binding buffer, a test compound (5 .mu.l) dissolved in DMSO was added. The reaction was then allowed to start by adding 0.01 ml (final concentration: 25 pM) of �.sup.125 I!CCK8. When a nonspecific binding amount was obtained, reaction was carried out in the presence of 1 .mu.M of non-labelled CCK-8. Reaction was allowed to proceed at 37.degree. C. in an aerobic phase of 5% CO.sub.2 and 95% air, after which the cells were washed with PBS. �.sup.125 I!CCK8 which had not been bound to the cells was removed, and the cells were lysed by adding 1% Triton X-100 (250 .mu.l) to the dish. Radioactivity of this solution was measured by a gamma counter. A specific binding amount was obtained by subtracting a nonspecific binding amount from a total binding amount. Using the thus-obtained specific binding amount, the percentage of the value obtained from a test substance addition group with respect to that of the DMSO addition group was calculated. The percentage was subjected to Hill conversion and then to a least squares method, obtaining a 50% inhibitory concentration (IC.sub.50).

In this receptor binding test, the binding inhibition (IC.sub.50) of the control compound (=compound A described in Example 1 of WO94/06825, i.e., potassium (.+-.)-1-�3-�3-�N-(3-methoxyphenyl-N-(N-methyl-N-phenylcarbomoylmethyl)-carbamoylmethyl!ureido!phenylethane sulfonate) was 1476 nM, and its receptor selectivity (IC.sub.50 ratio of CCK-A/gastrin) was factor 238. In contrast, the CCK-A binding inhibition of the compound of Example 92 of the present invention was 3640 nM and that of the compound of Example 87 was 3179 nM. Gastrin receptor selectivities of these compounds were factor 7280 and factor 3654, respectively, indicating remarkably high selectivities.

As described above, the compounds of the present invention have potent gastrin receptor binding inhibition or CCK-A receptor binding inhibition and thus are useful as therapeutic agents for the treatment of digestive diseases or central nervous system diseases. Of the compounds of the present invention, particularly preferred compounds have strong inhibition in binding assay with gastrin receptor and exhibit higher selectivity in inhibition of binding to gastrin receptors than to CCK-A receptors. Therefore, these compounds are particularly useful as preventive and therapeutic agents for digestive diseases such as peptic ulcers.
